Zen Tuner

This works. Solid, basic, application -- "does what is says on the tin." The default interface shows notation in concert pitch, but transposition is available if you play a transposed instrument (trumpet, clarinet, french horn, sax) -- a nice feature.

It does exactly what you need, no more no less. And a note to the writer of an earlier review she was having trouble getting the app to work. In my case, it worked fine on the pad forever, but I had to upgrade my iPhone to get it to work there, the retro download that was offered did not work. I would have titled this post “perfect” but that was used.

Just that.

It works!

Accurate, simple, free, add-less, and works exactly as expected! Helps me with my practice and doesn’t interrupt me! I couldn’t recommend an app more!

The frequency reading derived by this app is not accurate. Three other apps that I tested on my iMac and iPad derived the same tone frequency from my guitar and a test tone generator. This app is off by - 5.0 Hz. For example: a test tone of 80.9 Hz shows up as 82.4 Hz and a test tone of 181.6 Hz shows up as 185 Hz.

This App has issues. For one it doesn’t work. The App will open but freezes immediately and is not functional whatsoever.I’ve decided to uninstall this app .

A great tuner with a great developer! There was an issue with the tuner awhile back, but it’s all fixed now. Thanks, you rock!

I like this app which is way better on Mac than the tuner on guitar. The only thing is I have to set the system input as MacBook Air-Microphone. When I set the default input as my Rubix44 USB sound card, Zen Tuner stops working. Would you please make this beatiful and useful app able to work with external sound card?

I only have a USB audio interface for this mini; this app won't use it.
